Virtualization technology is popular today for hosting Internet and cloud-based compute services. Recently, the IP Communications domain has seen the adoption of virtualization with enterprise telephony solutions being hosted in virtualized environments. A deployment scenario that is common in the IP communications domain is the virtual appliance. A virtual appliance encapsulates the IP Telephony...
Mobile communication has been dominated by vertically integrated service provision in an `operator centric model', which has been highly bound to voice and SMS services and organized in a monopolistic competition between few Mobile network operators, MVNOs and SPs. In the recent years we have witnessed a radical change driven by the introduction and further development of smartphones, where we see...
In this paper, the embedded web server, which take Samsung corporation's ARM9-S3C2440AL processor as core, is designed, it's operating system is Linux, the system hardware architecture is presented. Then the process of the Linux operating system being transplated on ARM is introduced. The realization of Boa and dynamic interaction between browser and the embedded system by using CGI are especially...
Cloud computing can provide users dynamically scalable, shared resources over the internet, but users usually fear about security threats and loss of control of data and systems. This paper presents a practical architecture to protect the data confidentiality for guest virtual machines. With this solution, even the cloud computing service providers cannot access the private data of their clients....
Remote controlling of devices or peripherals interfaced with an MCU is essential in couple of applications in Embedded Systems. Web Server is one of the best solutions to do such task if internet is available at such remote locations. The important aspect of this paper is to port an open source Embedded Linux operating system on the FPGA to manage the hardware resources. It is pre-emptible and can...
Using wireless sensor networks is an effective way of gathering data and also opens up new sensing opportunities. Wireless sensor networks can be more useful if the data can be effectively retrieved from the sensor network. This paper describes the development of a gateway node for a wireless sensor network, implemented in TinyOS, using the AT91RM9200 ARM evaluation kit from Atmel. This node enables...
Bare PC applications do not use an operating system or kernel. The bare PC architecture avoids buffer copying, minimizes interrupts, uses a single thread of execution for processing network packets, and incorporates novel scheduling to minimize CPU utilization. We design a bare PC Web server that can serve both dynamic and static content. Measurements of response time, connection time and throughput...
Since the present computer systems use layered and modular architectures and execute the instructions in a number of different phases, therefore it has become an imperative to establish a trusted chain between various layers. It usually is integrity checking by hashing of executable codes. With guarantee of software integrity, the Web servers and other network entities can trust to client systems...
Using the cloud computing paradigm, a host of companies promise to make huge compute resources available to users on a pay-as-you-go basis. These resources can be configured on the fly to provide the hardware and operating system of choice to the customer on a large scale. While the current target market for these resources in the commercial space is Web development/hosting, this model has the lure...
With the rapid progress of VLSI and embedded technology, itpsilas the time to integrate traditional data-acquisition equipments and Web servers into an embedded system to get higher reliability, dependability and the real time performance.To this system, there are still exists some problems need to be solved effectively such as the implementation of multi-tasks running in concurrency mode. This paper...
Digital TV was introduced with promises for higher quality displays and converging Internet services which require more computing power and complex software systems. Such complexity entails a prolonged startup time that is similar to booting a computer system. In this paper, we propose two approaches to reduce the startup time of digital TV. Based on the suspend-resume technique employed in many commodity...
Increasingly popular approaches such as virtualization, cloud computing, and application development frameworks are changing the importance of the traditional operating system. Virtualization lets a single server host slices of multiple operating systems, each of which can run different applications within virtual machines. This makes the installation of any single full-featured OS instance a choice...
